brcmfmac: fix CLM load error for legacy chips when user helper is enabled
For legacy chips without CLM blob files, kernel with user helper function
returns -EAGAIN when we request_firmware(), and then driver got failed
when bringing up legacy chips. We expect the CLM blob file for legacy chip
is not existence in firmware path, but the -ENOENT error is transferred to
-EAGAIN in firmware_class.c with user helper.
Because of that, we continue with CLM data currently present in firmware
if getting error from doing request_firmware().
